Fastest Schiada Ever

[BoostPower]

There is little doubt in my mind there are a couple of 21 RC's out there that would run in the 115- 120+ mph range.. Ms Meads is one of them. Lee's dad's boat would be another I'd wager would run that quick.. They have ridiculous power in them.

I'm not sure how much faster you would want to go in a v-drive.

Not sure why Linder is sand baggin.. Pretty sure in one of our "evening cruises" I saw that GPS reading 116, and we were nowhere near racing / Wide open etc.. Fully loaded from fuel to coolers.

I am sure that their is a small handful of Schiada 21's 24's etc that have been put to some limits.
It really is a matter of how long they take to hook up under that boat.
We are now in testing stages with the new red boat and learning a few interesting things in the higher speeds. The v drive boats do eat up power, however they are a blast to drive. Video to come when I get back from Miami. I think you all will be impressed with 7700rpm, 60 gears 11-3/4" prop for starters at the 100 octane setting. Anyway, not much is impossible other then posting from an iPhone!😉

How fast is 1500hp, 55 gears, 12x17 prop@6300rpm?

My old 22' v-drive 540TT @1108HP 38 gear, 11.5x15 prop@5800rpm=102mph

Colburns 20' v-drive 468TT went thru the kilos in the 70s @105mph, I think Spanjians blown 20 was about a shade slower.

I heard several of the high end built 21s, (including Lees Dads boat) claiming 118-120mph.

Spanjin's 20' was a Naturally Aspirated 468 with hilborn injection, it broke 100mph in the kilos, i believe it was like 100.5mph. It was a race gas setup with such high compression that you had to index the spark plugs otherwise the piston would come up at top of stroke and squeeze the gap closed (basically it would take several boxes of plugs until you could find individual plugs to fit all the cylinders and torque down with the electrode facing up). It also had dry headers, but i think it was an all Iron motor. This was like 30 years ago, there is a lot more horsepower to be unleashed with today's Naturally aspirated setups from far better head porting and flow, and EFI tuning, valve train refinements etc....


Mr Meads boat is breaking 120mph, i wanna say it runs 122, it hauls ass.

Yeah, Linder isn't saying shit but his boat moves out pretty good.

his username is msmeads, he has some pictures posted on here somewhere, it's white with a lot of yellow and some blue stripes, big Brummett EFI turbo motor. It's also shown a couple times in the River Rats videos running at needles

 

[bump]

Seems to me I heard someone say that Randy Davis pulled Cory in SD and Davis said he was pulling Cory at well over 100 with plenty of pedal left.

That boat was fast, Trevor went told me that was the fastest boat they have ever had, including the nordic with a 1075. but doubt that. i think terry jessie has it now with an interior and a milder motor


Any idea how fast howard haigs carbon fiber 21 was? I remember Todd skiing that thing flat out way ahead of the pack when he was like 18 at parker

[hallett21]

How fast is the schiada evo? Does that have a different bottom than the rc?

Not to hate on the vdrive guys cause I think vdrive schiadas are really cool. But is it really worth all that money to not hook the motor up to an I/o or is it a reliability thing? Seems like you would get to the 120 mark a lot easier with an outdrive.

 

[BoostPower]

All the specs are great. I am happy for all with good handling fun v-Drives. Steve and I are close and he is welcome any time to run and evaluate my little red 21 or the blue one as he always extends the courtesy to me. Hek, i was running his stoker when i was 14 in Arrowhead. It's all good fun.
I will release the videos after the next magazine releases as promised. They put the two 21's I have on the cover of Performance Boats with a cool story. The boat will be at DESERT STORM and the LAKE HAVASU BOAT SHOW. 😉FYI the little red accelerates like 2 rockets!lol

The red Evo with the old 575 Merc runs mid 90's. Not bad for that power.

The other thing I must say is- The fastest boats are not just the ones that display fast passes on a few small intimate weekends. Their are a lot of other fast Schiada's out their that are not even in our region. Some of those guys don't care much to display their power as they build them for their own thrill, however we may all be surprised when they decide to show up! The old saying- Watch out for the quiet ones?😉

Ya but I think it is more than 10% with a v-drive often times.

My thoughts are that lift from strut angle plays into it. If your strut angle is 8* then with 0*=100% and 90*=0% then 8* would equal 9%. Even higher when you include the boat carrying the nose. So I'm thinking that 10% loss just in this would not be unreasonable. Then factor in prop slip on top.

My guess is that this also gets worse with speed along with prop efficiency, which is the reason that it starts to take way more horsepower to go a little faster with a v-drive. It's probably also one of the reasons outdrives are so efficient, you can dial the prop angle out at high speed.

All in all I still love v-drives

I went off the numbers from the 22' posted by skia. 113 theoretical, 102 actual is pretty damn close to 10%. Same basic style boat, heavy vdrive schiadas.

Hi there;
21's with over a thousand Horse power well run big numbers. Like the Boosts Power 21 we run 60's in the v-drive and that gear well be to small.
Now 60 gears are the largest gear we can run with a water jacket.
Top end number is one thing but the 60 to 110 in 3.5 is a rush that
you well never forget. there are a hand full of 21 running on the GPS
in the 120's. Lee and i test every one that leaves here complete with the engine builder.

 

[SKIA36]

I would think that the fastest Schiada is a 32 with twins. Maybe Stan can confirm this.

The SR 22 is not yet as fast as multiple 21s. It may have to get a Brummett PSI blown injected motor set on kill.

No. Use y2k Turbonetics turbos with our new housings. 2500hp easy! Bruuuuce

You can't couple that kind of power to a bravo drive, they are flimsy piles of garbage especially at that hp level. They no longer make #III #IV or #V drives which were a good intermediate size, and a #VI is really too big of a drive to put on a 21 RC. you could probably put one on a 24 with some good results.

 

[bump]

Barry knows all the secrets of that boat. But that was like 15+ years ago and things have come a long way since then. But I think at that time Lee told me that boat was for some reason 2-3 MPH faster than the rest. I think that is the boat he mentioned anyway...

Why were the 3,4.5's discontinued?

You'd have to ask Mercury about that and the genius business decisions they have made over the last 5-10 years, they have pissed a lot of their loyal customers off, and driven a lot of business to the competition.

 

[JBG]

Just to throw some numbers in to compare. In our TAF, we run 57 gears and a 11x16 2 blade prop. We went through the lights at 8200 and ran 168. So if the numbers that SKIA put up are evn remotely close, that thing is hauling serious donkey. :thumbsup

I guess Randy may have driven that boat one time to pull Corey. I pulled Corey in practice with it a number of times,, even pulled him to Catalina a couple of times practicing with it. It was Paul Chandler's old boat, and yes it was fast. GPS technology wasn't what it is now, so don't know we ever had a speed on the boat,, big gears,, big cubic inches, engine set pretty far forward.

We did a practice ski run at Parker one Friday on a race weekend, held the throttle until the boat was deep into the turn,, eased a bit and rolled back into it as soon as Corey was straight. I think guys still talk about that, certainly the fastest I ever pulled a skier through a turn!

Its not going within 45mph of the TAF,that why I've been pressing Grose to make me a prop. Trouble is he has issues with making a prop big enough. V-bottoms are a totally different animal.:bowdown::grumble:

thats some funny shit right there....might wanna try index washers instead of busting a piston or throwing a case of plugs away...

Does it really matter what yer running on the big end, isn't the real rush the neck snapping acceleration and how quick you get to that big number that makes driving the Schiada's so damn much fun...and of course the looks, and the ability to fly through chop, and of course the looks you get :thumbsup

No way B! Lower boost bigger volume, come on- don't be scarred they run 65-100hrs then rings bearings and such!😉

We tried the biggest prop they had, it would barely get on plane, was awesome acceleration from 50mph to 100mph and then we hit the rev limiter @6800...

You have one of those "cheater" Schiadas though, and you need old #34 to tell you when to shift the dang thing!

Barry I know Steves boat is longer and has more power than mine I was still suprised that Joeys prop would be so far off.I have no doubt what Steve says is correct. As far as shifting goes I may have to put a race pak in and auto shift it ......

Ron Spindler - 21 RC 850 HP - 104.75 mph That was back in 1983 at the PowerBoat Time Trials.

Ron's Current playboat - 45% more power then the old boat.

Back in the 90's - 900 to 950HP would get you 102-110mph depending on weight and setup.

Why would they get slower? With all the new technology in hull construction, materials and engines i would have thought everything would be lighter, faster and stronger.

 

[Its good to be King]

Funny, how the haters always have opinions with there vast knowledge. But nobody is talking about any other v-bottom boat that is approaching 100 mph like the Schiada's

Hallett vector and 210 sorry I had to lol

In the 90's there was no GPS speedo, people were either gauging speed on peedo tubes, or were lucky enough to have someone with radar, hitting 110 in the 90's was pretty topped out. they've come up to 120 from 110, that's pretty good, but you have to remember this is a 30 year hull design, the 120's is where these boats are gonna peak in my opinion.

Also, the schiada's work way better heavy, they actually run better heavier, with more horsepower, than light with equal or less, weight is your friend with that hull design, you need the inertia to push the water into submission. The newer european/aus style 21's are much narrower and knife through the water, not relying on their weight as much to push through.

 

[Schiada Time]

I aggree Shane (Racey). My 22 plows through the chop and being a 74 it is laid up heavy. The only bummer is it is going to take 1,000 HP to get it really moving.

 

[AFUEL7067]

1000 hp in a Hallett and youve got a gdamn certified Rocketship...

The vector is a schiada splash so scratch one hallet and the 210 doesn't work as a v-drive and takes big big power to go fast

Have you ever looked at the differences between a Vector and 21RC's bottom or top? Not a splash.....
